SPINDLE-DRIVING DEVICE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 415,827, dated November26, 1889. pplicatiou filed June 4, 1888. Serial No. V275,930. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOSEPH E. TYNAN, of Paterson, in the county ofPassaic and State of New Jersey, have invented an Improvement inSpindle-Driving Devices for Spinning-Machines, of which the following isa specification.

My invention is especially designed for use in that class of machineryin which either a single thread is twisted and wound or two threads aretwisted, doubled, and retwisted and wound; but my said invention may beused in other kinds of silk -twisting machinery and also in machineryfor twisting cotton or other thread.

Vhere the spindles of a spinning-machine are each driven by a separatebelt, as is generallythe case, said spindles are not always all drivenat the same rate of speed; hence there is inequality in the twist givento the threads. This irregularity of speed of the spindles is caused bythe slip of the belts upon the spindles and driving-drum' and by thevarying tension of the belts.

An endless belt has passed along between two rows of pulleys to drivethem simultaneously, as in English Patent No.1,938 (old law) and UnitedStates Patent No. L1,215 to W. Baxter, and spindles for spinning havebeen driven by such pulleys, and in some instances several spindles orgroups of spindles with pulleys have been driven by one endless belt;but in case of one thread breaking it either had to be joined whilerunning or else all the spindles had to be stopped, and where stopmechanisms have been provided for each group of spindles they haveeither had separate belts or else were driven by frictionwheels that inpractice are found to be more irregular than belts.

In my improvements I employ one endless belt to drive numerous groups ofsupply and lay-up spindles, the belt passing between the pulleys of eachgroup, so as to drive the layup spindles in the reverse direction to thesupply-spindles, and I combine with this a drop-bar-stop mechanism toeach group, so

from being moved by the contact therewith of the traveling belt, and incarrying out this invention I cause the pulleys to press against thebelt by the force of springs and swing' them away by a positive action.

In the drawings, Figure 1 is a plan view showing my improvement appliedto a silk doubling and twisting machine, only a portion of the machinebeing shown and the spindles being represented without their spools orlbobbins. Fig. 2 is an elevation of the parts shown in Fig. l, with thespools or bobbins upon the spindle. Fig. 3 is a sectional elevation atthe line Qc of Fig. 2, the parts being shown in larger size. Fig. 4 is aseotional plan at the line y 'y of Fig. 3. Fig. 5 is a rear view of thelower end of the dropbar, showing also the ends of the spindle-carriersoperated by said drop-bar.

A A are the frames ofthe machine, and B the spindle-rail supported bysaid frames A A.

In Figs. I, 2, 3, and 4 the spindles are shown as arranged in groups ofthree, as in Letters Patent No. 364,783, granted to me June 14, 1887.The spindles 3 3 carry the spools 6 6, that supply the single thread,and these threads, after being twisted, are laid together and wound uponthe spool 8 of the spindle 5.

9 is the ring-rail carrying the ring-travelers, and this rail may beactuated in any manner for laying up the threads upon the spools 8.

The spindles 5 are supported and revolve in bolsters a, secured to therail B, (see Fig. 3,) and said holsters are ranged in a straight linelengthwise ot the machine. The spindles 3.3 are in a line parallel withthe spindles 5; but their bolsters or bearings f are mounted uponsupports or carriers c c, pivoted at to projecting portions of the railB.

E is the endless belt for giving motion to the two rows of spindles.This belt is carried by the drums F G upon shafts 13 14, respectivelysupported in bearings I-I II upon the fra-me A, and motion is given tothe belt by a belt from the driving-shaft of the machine passing arounda pulley 16 upon the shaft 14. The endless belt in its travel passesbetween the two rows of spindles 3 3 and 5, and said spindles arerotated by the contact of the edges of the belt with the pulleys a a andfi fi upon the spindles. The arrows upon Fig. l indicate the directionof travel ot' the IOO ' lof belt E and the direction of rotationof thespindles 3 8 and 5, the spindles 3 3 rotating in the opposite directionto that of the spindles 5, so as to give the proper twist to the singleand doubled threads.

In order to keep the endless belt in Contact with all the spindles ofthe two rows, I mount the spindles 3 3 upon pivoted carriers c c, asaforesaid, and I provide a helical spring hfor each pair ofspindle-carriers, as shown in Fig. 4, which springs draw the longer armsof said carriers toward each other and bring the pulleys a a of saidspindles 3 3 against one edge of the endless belt, thereby forcing theopposite edge of therbelt against the pulleys t1' of the spindles 5andinsuringuniformity of contact of the belt with all the pulleys of thetwo rows of spindles. The longer arms of the spindle-carriers c c extendbeyond the rear of the rail B and receive between them the doubleinclined end ot' the link or drop-bar D, which drop-bar D is to beconnected at its upper end to the lever of a stop-motion device,preferably such as that shown in my application for patent, Serial No.256,728, filed December 2, 1887, it being understood that there is adrop-bar for each group of spindles 3 3 and 5. lWhen a drop-bar of anygroup of spindles falls from a thread breaking or otherwise, theinclined end of said drop-bar acts upon the longer arms of saidspindle-carriers c c and causes said carriers to swing upon their pivotsc, andthe pulleys a a of that group of spindles are moved away from thebelt and brought into contact with the spring-brakes l Z, which arresttheir rotation. At the same time the spindle 5 is stopped by the arms mof the dropbar coming into contact with the top surface of the pulley z'of said spindle 5. When the drop-bar is raised by the attendant afterthe broken thread has been joined, the pulley t of the spindle 5 isreleased and the spring 7L swings the spindle-carriers so as to move thepulleys a a away from the brakeslland into contact with the edge of thebelt E, .and the group of spindles is again put into motion by saidbelt. By thisimprovement all the spindles of each row will be driven atthe same rate of speed, as there is a constant and uniform pressure ofthe pulleys againstthe belt. The drop-bar D is guided in its movementbythe pin d, projecting from the end of the oiltube (l5 and passing into aslot in said dropbar.

It is necessary that the endless belt should travel in a straight line,or nearly so. If the endless belt is not sufficiently stiff, thepressure of the pulleys a a against said belt at` places where there areno idler-pulleys opposite said pulleys a a might bend said belt andcause its edges to travel in undulatory lines, and the spindles 3 3would be moving out of line of each other, which would interfere withthe spinning operation. To prevent this I stift'en the endless belt by aband 't of sheet metal secured to the belts by rivets.

This metal baud may be between the two thicknesses of leather of thebelt,it the beltis of two thicknesses; or it maybe applied to the outersurface of thebelt, as shown. In either case it prevents the beltstretching and stiftcns it so that the belt will travel in a straightline and thereby keep all the spindles of the single row in line witheach other.

I claim as my inventionl.
